使用CreateProcess创建新的process 并返回process运行结束返回值

转载这篇主要是记住:获得create的新进程运行结束时的返回值的方法

如下:

  1.  
    #include <malloc.h>
  2.  
     
  3.  
    DWORD run_Execute(LPCTSTR lpszFile, LPCTSTR lpszParam)
  4.  
    {
  5.  
    DWORD exitCode = 0;
  6.  
    PROCESS_INFORMATION pInfo = {0};
  7.  
    STARTUPINFO sInfo = {0};
  8.  
    sInfo.cb = sizeof(STARTUPINFO);
  9.  
    sInfo.wShowWindow = SW_SHOW;
  10.  
     
  11.  
    int nCmdLen = (_tcslen(lpszFile) + _tcslen(lpszParam) + 2) * sizeof(TCHAR);
  12.  
    LPTSTR lpszCmd = (LPTSTR)_alloca(nCmdLen);
  13.  
    memset(lpszCmd, 0, nCmdLen);
  14.  
    _tcscpy(lpszCmd, lpszFile);
  15.  
    if(lpszParam)
  16.  
    {
  17.  
    _tcscat(lpszCmd, _T(" "));
  18.  
    _tcscat(lpszCmd, lpszParam);
  19.  
    }
  20.  
     
  21.  
    if(CreateProcess(
  22.  
    NULL, //LPCTSTR lpApplicationName, // pointer to name of executable module
  23.  
    lpszCmd, //LPTSTR lpCommandLine, // pointer to command line string
  24.  
    NULL, //LPSECURITY_ATTRIBUTES lpProcessAttributes, // process security attributes
  25.  
    NULL, //LPSECURITY_ATTRIBUTES lpThreadAttributes, // thread security attributes
  26.  
    FALSE, //BOOL bInheritHandles, // handle inheritance flag
  27.  
    0, //DWORD dwCreationFlags, // creation flags
  28.  
    NULL, //LPVOID lpEnvironment, // pointer to new environment block
  29.  
    NULL, //LPCTSTR lpCurrentDirectory, // pointer to current directory name
  30.  
    &sInfo, //LPSTARTUPINFO lpStartupInfo, // pointer to STARTUPINFO
  31.  
    &pInfo)) //LPPROCESS_INFORMATION lpProcessInformation // pointer to PROCESS_INFORMATION
  32.  
    {
  33.  
    // Wait until child process exits.
  34.  
    WaitForSingleObject( pInfo.hProcess, INFINITE );
  35.  
     
  36.  
    if (GetExitCodeProcess(pInfo.hProcess, &exitCode))
  37.  
    {
  38.  
    TRACE( _T("Exit code = %d/n"), exitCode);
  39.  
    }
  40.  
    else
  41.  
    {
  42.  
    TRACE( _T("GetExitCodeProcess() failed: %ld/n"), GetLastError());
  43.  
    ASSERT(0);
  44.  
    }
  45.  
     
  46.  
    // Close process and thread handles.
  47.  
    CloseHandle( pInfo.hProcess );
  48.  
    CloseHandle( pInfo.hThread );
  49.  
    }
  50.  
    else
  51.  
    {
  52.  
    TRACE( _T("CreateProcess() failed: %ld/n"), GetLastError());
  53.  
    ASSERT(0);
  54.  
    }
  55.  
     
  56.  
    return exitCode;
  57.  
    }

  1.  
    //测试示例
  2.  
    run_Execute(_T("notepad.exe"), _T("c://temp//aa.txt"));
